10 20 30 a) b) 链由三重螺旋变为四重螺旋（图1）[4]。我们将看到我们在本文中考虑的聚合物如何具有与全同立构聚苯乙烯非常相似的结构。事实上，即使是对两种聚合物的粉末光谱的检查也强调了它们之间的密切相似性，至少就晶胞的形状和尺寸而言是如此（图 2）。
10 20 30 a) b) the chain changed from that of threefold helix to that of a fourfold helix (Fig. 1)[4]. We shall see how the polymer we are considering in this paper has a structure strongly similar to that of isotactic polystyrene. Even an examination of the powder spectra of the two polymers, in fact, emphasizes the close analogy between them, at least as far as the form and dimensions of the unit cell are concerned (: Fig. 2).
